This doesn't have the new -ac testing stuff from 2.4.21pre5-ac but it
has the stuff I now trust in it. This fixes the cache flush stuff and
also means ide-disk now should be safe shared IRQ

Dave Woodhouse did this a while ago and its been kicking around in my
tree just fine. This gets rid of a lot of the init lists of functions
still left in the kernel by having an __init type array built up for the
consoles as well

We must not look for a PCI IRQ for a non native mode IDE device
We must write PCI_INTERRUPT_LINE for VIA

ALi Magik requires workarounds for TV chips
IDE controllers require proper handling in legacy mode
PXB must be disabled on C0 450NX or the IDE will corrupt memory
VIA northbridge devices require the interrupt line is written
NEC_CBUS_2/3 require ISA DMA workarounds

This chip needs latency and other setups to avoid a PCI/AGP deadlock
with tv cards

The -ldb has to be at the end sometimes

 - Cleanup Makefile.
 - Fix potentional crash in dv1394 module unload.
 - Why does ARM's memcpy not return void*? Oh well, work around it in
  eth1394 by not expecting standard behavior.

 - Inode and dcache Hash table only needs half the memory/cache because
   of using hlists.
 - Simplify dcache-rcu code.  With NULL end markers in the hlists
   is_bucket is not needed anymore.  Also the list walking code
   generates better code on x86 now because it doesn't need to dedicate
   a register for the list head.
 - Reorganize struct dentry to be more cache friendly.  All the state
   accessed for the hash walk is in one chunk now together with the
   inline name (all at the end)
 - Add prefetching for all the list walks.  Old hash lookup code didn't
   use it.
 - Some other minor cleanup.
